Indeed. There actually might even be someone who has tried exactly that-- I don't know why they would-- it would require a completely new Win 8 kernel to be recompiled to go with the ARM processor these use. But who knows-- somebody probably did that, somewhere or other.

Me, I'm happy to have a product that is neither Apple nor Microsoft....

Isn't WinRT 8 for ARM devices? Or aam I misremembering what I read yesterday?

That would be correct. But I seriously doubt that IF someone did get Windows RT installed on a TF that it would be acceptable as the tablet specs for Windows RT are such that there isn't currently a tablet on the market that can come really close.

Also, as it stands now, Windows RT has a secure boot loader which may preclude anyone from either dual booting or going back. At least for now.
